Monopoles <br /> All three technologies use monopoles (Figure 5), although their heights and designs vary. Ranging <br /> in height from 25 to 125 feet, monopoles consist of a single pole, approximately three feet in <br /> diameter at the base, narrowing to roughly 1.5 feet at the top, and may support any combination of <br /> whip,panel, or dish antennas. <br /> Figure 5 <br /> ^^1��� WHIP ANTENNAS <br /> MONOPOLE �� .0-10 PANEL ANTENNAS <br /> O, DISH ANTENNA <br /> EQUIPMENT <br /> BUILDING <br /> Monopoles are generally used in rural areas, near freeways, or in areas where buildings are not of • <br /> sufficient height to meet line of sight transmission requirements. In the cellular mobile phone <br /> system, monopoles are used much more commonly than lattice towers. AirTouch and GTE <br /> Mobilnet have constructed approximately 65 monopoles in the San Diego area. Nextel, an ESMR <br /> provider, also uses monopoles, and has built four in the region. <br /> Monopoles in PCS systems are expected to. be shorter than those of the cellular telephone and <br /> ESMR systems. Some PCS providers are proposing an integration of monopoles into existing light <br /> poles. Illustrated in Figure 6, this type of facility may be referred to as the "flower tower." <br /> I <br /> Figure 6 ANTENNAS <br /> FLOWER TOWER <br /> / <br /> / <br /> . <br /> EQUIPMENT <br /> BUILDING <br /> 14 <br />
